Hi Henrik,
I come up with another related problem: How to keep a record of all the information at one time?
In my project, I use solid module and Darcy flow model to simulate the Biot theory.
First I run the coupled model to get an stable status(p_initial, u_initial), and use this status as a reference for later use, i.e. some equations involve (p-p_initial) or(sx-sx_initial) . Then I change the boundary condition, and let the simulation continue.
My problem is how to keep and then how to use this reference status? Previously, I run two sets of models: model 1(with p_initial and u_initial as independent variables) runs to equilibrium, and the running time is (0 to 100 s); model 2 uses the results from model 1 as initial values, and proceeds. In model 2, I used some equations involve (p-p_initial).
I just noticed maybe it's wrong to simply use (p-p_initial), since they are not corresponding to the same time.
Can you give me some clue on how to use the information at a specific time step?
